DM6437 EDMA configuration

Marcio

Hi, I´m new with DSP and I need to configure an EDMA chanel in my code. But I don´t know what´s the best chanel for configure it.

Could someone tell me it and if possible tell me where I find an example.

Thank you.

Many of the EDMA channels are mapped to specific hardware events as shown in table 6-6 of the datasheet, so you would typically choose a particular channel based on what event you want to drive the EDMA transfers.

As to an example, the application note below explains how to use the EDMA3 driver on the DM643x series that should be helpful in getting EDMA functionality in your code.
